"Hey, Peebs!"

Finn kicks open the door and is squirted in the face with cream.

"Augh!" He takes a lick, "Mm! Vanilla!"

"AHH!" A pink, gummy guy runs past him, hiding behind Fiona. Princess Bubblegum trails behind with her cream gun.

"Outta my way, Finn! That guy's an imposter!" She points the gun. Fiona draws a scepter with ribbon that sprouts a sword.

"F-Fiona! That girl's crazy!" The pink guy cowers behind Fiona.

"Wait! Wait!" Finn jumps in between the two, "Peebs, hear me out. And you, whoever you are..."

Fiona takes a protective stance,"This is a Prince, Finn. Prince Gumball."

Jake rubs his eyes. How did he not see it?! Fiona and Finn were lookalikes... And now there was this guy who looked like Bubblegum! Except he was a guy... Wait a minute... Prince Gumball... Where had he heard that?

"Why were you spraying cream at 'im?" Finn asks PB.

"He came outta nowhere, Finn. Freaked the heck outta poor Starchy in the process. The banana guards came calling and I saw that he was trying to masquerade as me!"

"Whoa, whoa! I was not masquerading as anyone!"

"Uh – but... PB is the only person I've seen made of bubblegum. She is Princess Bubblegum."

"Princess?! When did this happen?" The Prince bursts out.

"Okay, guys," Finn puts his arms up, "Let's sort this thing out. Anyone thirsty? Let's talk this thing over tea. C'mon."

Fiona and PB lower their weapons. Gumball stays behind Fiona.

"Alright," PB claps her hands, "Let's get sorted out."

At her command, Peppermint Butler comes out. In his hands, he balances numerous cups and saucers. Regally, he arranges them in a circle on the royal carpet and pours sugar tea for six. He takes a bow and leaves as quickly as he came. Finn and company make themselves comfortable in the castle main hall.

"Whoa! What the dingdongs?! Who's this?" PB, finally noticing, jabs a finger at Fiona.

"Huh? Oh, she's Fiona. A human like me, PB! Isn't that great?"

"But... That's impossible..." PB sputters, "Finn, she looks-"

"Wait, you're human?" The prince looks at Finn incredulously, "But... Fiona is the only human in Aaa-"

"Psst," Fiona tugs his sleeve and whispers in his ear, "Gumball, apparently, we're not in Aaa anymore. This place is Ooo, or something..."

"Ooo?"

"You're not from around here, are you?" PB looks at the two of them skeptically, "Where is this Aaa?"

"It's where my kingdom is. The Candy Kingdom," The Prince looks at PB's shocked face, "What?"

"C-Candy... Kingdom?" PB is at a loss for words.

"Whoa, whoa, whoa. That's impossible. PB made the candy Kingdom. There's nothing else like it anywhere!"

"Umm, I'm sorry, yellow talking dog, but I built my Candy Kingdom and I thought it was the only one. That is... Until I wound up here..." The Prince looks about the cake walls, "Incredible. It looks exactly like my palace..."

"Well, that can't be. I used a unique material from rare gumberries that only I know how to cultivate. I have the only bush in all of Ooo-"

"No way!" The prince practically jumps up, "I used gumberries! And only I have access to my source in my secret lab!"

"Secret lab?" Fiona looks at Gumball, puzzled. Gumball ignores her. He is intently locked in a staring contest with Bubblegum.

"What the buzz is goin' on?!" Finn looks about, lost and bewildered, "How can they both – They're so... alike..."

Cake and Jake exchange looks. A nagging feeling bites at Jake to recall something important, but he is unable to. All he can tell right now is Finn and PB have both been cloned... very wrongly.

…

"Hey... Hey!"

Marceline opens one eye cautiously. She stares up to a boy's face. One the same skin tone as her, with ragged black hair and red eyes. He wears a plaid red shirt and has long canines. Most shocking of all, he has two red puncture marks on the side of his neck. Like she does.

"Hey... You alright? Sorry 'bout that, but you shouldn't have crept up on me like that..."

"Ugh!" Marceline sits up suddenly and pushes him off. A red welt stung across her clavicle.

She'd heard a sound near her cave as she was just lounging. She came armed to find the source among the trees. Then this... guy just jumps out and smacks her across the chest with the backside of his ax. She fell over and all of a sudden, he's on top of her.

"Says you... You're sneaking around vampire territory, you know?" She fingers the bruise. It fades rather slowly. His ax must be made of a harmful material, like Nightosphere metal, or Underworld ore...

"Oh?" He smiles smugly and eyes the red marks on her neck, "Where' the rest of you?"

Marceline makes a growling sound, "This area... all the way to the river; it's my turf. And I'm Marceline Abadeer, the Vampire Queen."

She floats a few inches above ground to intimidate him. He floats also and lazily circles her as he lay on his back, observing her. She watches him carefully.

"Queen, eh?" He says it mockingly, not taking his eyes off her, "Well, I'm son of the Vampire King, heir to the Nightosphere, yada yada... But I don't remember anything about a queen."

Marceline recoils slightly from his stares, "...Who are you? The Vampire King died a while ago. He turned to ashes..."

"Yeah, I know. And he named me his heir. So now I can either rule the Red Throne or the Nightosphere. Choices, choices..."

"You can't be the heir. I'm the heiress to the Nightosphere. Hunson Abadeer is my dad!"

"Whoa, chill! I don't know who's this Hunson guy, but my mother, Helga – she's the ruler of the Nightosphere."

"Helga – What-?!" Marceline had never heard of something so ridiculous.

"Anyway, you got a pad I can crash?"

Before she can respond, he zips past her and discovers the cavern she'd been living in.

"Wow! Nice..." His voice echoes, "Called it!"

"GET... OUT!"

Marceline pulls out her two-bladed ax bass from her harness and lashes it viciously at him. He dodges and whips out his one-sided ax, adorned with a skull. Their axes meet with sparks. Both grapple, as they both are surprised.

"You... have an ax bass?" He speaks first, "But I … Only I have one..."

"And you..." Marceline hadn't noticed the six strings before. She was sure only she owned this kind of an ax in all of Ooo. The ax was an heirloom she turned into an unique instrument...

"Who are you?"

They both put down their weapons and look more thoroughly at each other. He says his name. Marceline's dead heart almost jumps for the first time in 500 years. Her eyes widen as her eyes adjust to that body and she remembers. She had given him that name. That face... He...

"I'm... Marshall. Marshall Lee."
